...excitability in two ways: by overexpressing a leak potassium
channel or by inhibiting AMPA receptor trafficking. In both cases, there was a compensatory increase in membrane excitability as a result of increased amplitude of voltage-gated sodium currents. From Ribbon Synapses to Spike Trains Peter Heil,...
New mechanism links smoking to lung damage
...and out of the cell, including calcium, sodium and potassium
ions, each of which passes through a specific type of channel. Hemichannels, however, with ports nearly twice the size of an ion channel, are not as specific, permitting more rapid, less regulated flow of molecules up to the size of 1000 Daltons--...
Acute sleep deprivation leads to changes in nighttime urine production for men and women
... II and aldosterone and the increase in sodium and potassium
excretion. The relatively higher blood pressure on sleep deprivation nights may also have affected the blood pressure in the kidney producing an osmotic diuresis. The researchers found that during nighttime, acute sleep deprivation leads to: ...
